IMPROVEMENT IN MACHINES'FOR MEASURING, STRETCHING, AND SKEINING SILK.

The Schedule referred to in these Lettera Patent and making pai-t of the same.

I, .SAMUEL K. 'Sturm-'of the city of Newark and State of New Jersey, have invented certain Improvements in Machines for Stretching Silk in the Gum, of

which the following, whentaken in connection with .Figure 4 is an end View of the upper swift, showing f the adjustable arms.

Heretof'ore the silk has been run offfrom the bobbins onto a roller oi' wood or metal, and from thence onto another roller of the same description, and from thence onto-bobbins again, and from thence onto a reel to be skeined, which requires the labor of two persons and two. separate machines.

By the use of my invention the process is greatly simphed, as it requires but one machine-and one `person to operate it, and about one-halt` the time to per- Yform a given amount of labor.

Toenable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.-

In the first place I construct a frame, which should' be made of metal.l In this frame are placed two swifts, a and b, of any required size, one above the other, but their axes are not in a perpendicular plane, for if so the tension would all be upon one arm of theswifts; but .the top swift a should be far enough to one side so that the tension will be upon two arms of the switts. The shaft of the top swift a has a hinged box or bearing, soithat when the silk is skeined the topof the box maybe' removed, and the end of the swift raised, and the skeins removed by or from this end.

In order to loosen the skeins, vso as to facilitate their removal, the bar c is made adjustable, so that it may be'forced downward, thus loosening thei'skeins -that they may be easily removed.

The lower swift b is that upon which the silk is first wound from oiithe bobbins, vand upon it'tlie silk is also measured; and for this purpose a device is arranged at one end of the machine in the following manner:

Near the end of the shaft d is formed a'worm-gear, e, which meshes into a correspondinggear, jl

per`swift a., by which Upon theback end of the shaft g` which passes through the gear j, is a thread, upon which isplaced a nut, h, which-does not 'turn with the shaft g, but is held in position by a wire,- t', orv its equivalent,'which prevents the nut from turning, and at the same time allows it to movebackward and forward as far asrequired; and when the nut hpresses against the gaugepin j, which passes'through the shipping-bar It, and forces the bar k out from thenotch l in the arm m, it is drawn back by the spring a at the bottomof the bar k,`andthrows the. belt, which drives the machine,

off onto th'e loose-pulley, and the machine stops.

The notches in the gauge-pin j a're for the purpose of setting the pin so as to measure a givennumber'of yards on the. lower swift 71'. This is an important'part ot' the machine, as it enables the operator to measure any required number of yards at thesame time that the silk is taken from the bobbins.

After the silk has been measured on the lower swift -b andthe machine has been stopped, the end of the silk is fastened to the upper swifta, and a belt is ad-` usted upon the other pulleys o, and the'motion of the swifts is reversed, and the silk is wound upon the upprocess. it is also stretched and skeined. Y

In order to stretch the -silk the gear p upon the lower swift b should be proportionately larger thanv the two upper gears, the proportion to be in accordance with the amount of stretching required, which may be more or less.

Before starting the machine for the purpose of stretching and skeining the silk, the gear f, which is adjustable, should be moved backward upon the shaft until it is out of gear, when the weight 2, which is secured by a cord to shaft g, will drop, and, turning the shaft g, adjust thenut h into its proper place; and after the operator has removed the silk from the upper swift he has but to readjust the gear f so as to mesh with the worm-gear e, when thev machine is ready for the first process of winding the silk from oi the bobbins.

Near the bottom of the machine in front is a sliding bar, fr, creased at equal distances, which is for the purpose of securing uniformity in the winding of the silk, each thread passing through one of the creases in the sliding bar 'r above'mentioned.

The ,sliding bar r is operated by means of an adj ustable lever, s, at the right end of the machine, which lever is operated by means of a grooved cam on the end of the shaft d, a stud in the end of the lever s titting and sliding in the grooved camt.

The sliding bar lr is secured in a slot or mortise o n the lower` end of the lever s.- The extent of the horizontal motion of the sliding bar is regulatedby means of the lever s, which is adjustable.

Havingv 'thus fully described its construction and operation,

What I claim as new, and desire to secure by Letters Patent, is-

1. The swift a, carrying the adjustable armv e, in combination with the swift b, lever s, cam t, and the gear mechanism, substantially as herein shown and described.
